    Rescale TPS for 102mm TB?

    I was wondering if part throttle driveability might be improved, or improvable. It kind of has the sensation of a weak accelerator pump, but it doesn't really bog, it just seems lively when the throttle is just cracked. Then it seems like a little more throttle does not increase the acceleration. I'm just thinking out loud while I'm stuck in traffic. Any thoughts? I'll try to find a log later, if anybody is interested.

    Your TPS settings are correct? TPS is in "idle" mode at idle, right?

    The VE table is the primary "accelerator pump". What's the wideband saying when you feel the flat spot?
